Question

The measure of the vertex angle of an isosceles

triangle is 76 . Find the measure of a base angle.

Answer 1

52

Explanation:

Let each of the base angles = x

x + x + 76 = 180 Subtract 76 from both sides

x + x = 104 Combine the 2 xs

2x = 104

x = 52

Each base angle has a measure of 52
